LogicalLink.

A logical link connects two logical ports. It doesn't contain information about the intermediate nodes and links in the path connecting the two end points of the connection object. For example, FrameRelay PVCs and ATM VPCs and VCCs are modelled as logical links.

In general, all these objects have an alarm state and an operational state. The TA developer must define rules in order to model the network technology within the INMS data model, as well as rules to assess the alarm and operational states of the network components supported by the new network technology. A prerequisite to develop a reasonable technology adapter is that the network technology to be integrated provides MIB objects for:

• The modelling of the network technology within the INMS data model as described above. For example, if the new network technology supports ATM PVCs, which is the case with Fore's technology, the corresponding agent MIB must provide objects that allow the definition of the corresponding Gate MIB objects, e.g. gateAtmPvcSrcVci (source VCI) and gateAtmPvcDstVci (destination VCI).
• The definition of Gate operational and alarm status MIB objects for those network entities supported by the new network technology. For example, if the new network technology supports ATM PVCs, the corresponding agent MIB must provide MIB objects that allow the definition of the operational status of the entire PVC, i.e., the gateE2eConnOperStatus MIB object.
